Summer is back. Therefore I was thinking about the settings on the Evolution system. FWIW, I'm very happy with this Bryant system. Very comfortable all winter.
To the point. The control has 3 settings for AC Airflow: Maximum, Comfort, Efficiency.
I'm going to pull out the manual later - but any hints. I've had it on Comfort the whole time.
I have a MAA315 Evolution 80, York 2 Ton, ADP 3 ton with TXV (approved for 2,2.5,3 ton flow).
I keep wanting to set the outdoor unit as a 2.5ton. It just seems that the airflow is so low with 700CFM (2 ton). Especially when this thing kicks into Dehum - 450CFM! Tiny. I have no idea how this thing will keep up on a 100 degree day as I've put in R-49 (had R-22 if that) insulation in the attic in the fall - so who knows what I'll get this summer. When I purchased the system I cacled it around a R-49 house and sized it right. The old system I took out was a giant 3.5 Ton Trane from the Mid-80s.
I get hung up on this CFM boost more than anything. I want to set it at 875. The coil is big enough, the York is rated at 400CFM/ton or 800CFM. So that doesn't seem like a bad idea. In some way I think I'd get 'higher' efficiency because the condenser would run less time. My concern is I'll jack the humidity control, increase static pressure and just defeat the purpose of comfort.
Any thoughts on the AC Airflow setting and putting the thing as a 2.5 or a 2.0 Ton?
